Patent GB-370585-A (GB)
Title: Improvements in rotary fluid pressure engines
IPC: F04D5/00
Filed: 1931-02-27
Abstract: 370,585. Centrifugal pumps. GILKES & GORDON, Ltd., G. and CREWDSON, E., Kendal, Westmorland. Feb. 27, 1931, No. 6135. [Classes 110 (i) and 110 (iii).] In a centrifugal pump the runner 14 is formed with vanes 21, Fig. 5, on one side, which are encased in a shrouding 22.

In an alternative arrangement a double-sided runner is used, and the suction and delivery pockets in the casing walls extend 270‹ and 90‹ approximately respectively.
Patent GB-626152-A (GB)
Title: Improvements in and relating to thermionic valve circuit arrangements for handling impulsive electrical variations
IPC: H03K3/04
Filed: 1947-03-04
Abstract: 626,152. Pulse discriminating circuits. THOMAS, D. G. A. March 4, 1947, No. 6173. [Class 40 (vi)] A circuit for producing an output pulse only when an input pulse exceeds a certain amplitude comprises a pair of mutually coupled valves, the first valve 1 being normally non-conducting but rendered conductive, by an input pulse of sufficient amplitude to cut-off the normally conducting second valve 2. The cathode of valve 1 is connected to a low potential over cathode load 5 and to a suitable potential through a rectifier 4 so that the cathode is normally maintained at this potential but follows the control grid when the valve is rendered conductive. In the normal state, valve 2 conducts, the grid being held at earth over diode 19. The grid resistor 15 of valve 1 is returned to a point, negative with respect to earth so that valve 1 is cut off, diode 4 conducting to maintain the cathode of valve 1 at the same potential as that of valve 2. The time constant of the coupling network 18, 20 is made long compared with the pulses to be handled. An incoming pulse of sufficient amplitude causes valve 1 to conduct and hence valve 2 to cut-off, the valve 1 acting as a cathode follower so that overloading in the presence of a large amplitude pulse is avoided. A pulse of suitable length is generated by the line 21 and fed through the cathode follower 23 to the output terminal. In order to avoid short input pulses being fed to the output, the anode resistor 17 of valve 1 is connected to the anode of valve 23 so that valve 2 may not be rendered conducting by the termination of the input pulse until the pulse from line 21 has ceased. A paralyzing pulse may be fed to the suppressor grid of valve 2 after each operation.

Title: Improvements in or relating to hydraulic control apparatus
IPC: B23Q5/26
Filed: 1949-03-08
Abstract: 698,321. Drilling-machine details. FIELDING & PLATT, Ltd., ROWLES, R. V., and ELY, H. J. June 26,1950 [March 8, 1949], No. 6296/49. Class 83 (iii). Means for controlling the distance moved by a hydraulically-operated carriage of a drilling or other machine-tool comprises a hydraulically-operated device 1 arranged to grip a trip-rod 10, which, after a predetermined movement of the carriage, actuates mechanism controlling a valve which in turn controls the hydraulic operation of the carriage. As applied to a drilling machine in which a progressive feed, with intermittent withdrawals to clear swarf, is given to the drill carriage, a hydraulic cylinder 1 on the carriage is connected by a pipe 3 to the main cylinder driving the carriage so that, during initial feed, the spring-loaded piston 2 slides over the rod 10 until the drill begins to cut and the increased resistance builds up the pressure in the main cylinder sufficiently to cause the piston to grip the rod and carry it along with the carriage. The rod then rotates a lever 12 about its pivot 13, and tensions a spring 16 connected between the lever and the midpoint of a toggle quadrant 17 connected to the spindle 18 of the control valve. When the lever has moved sufficiently for a peg 20 on the quadrant to clear a cam surface 19 on the lever, the spring 16 turns the quadrant suddenly through 90 degrees, as limited by a stop 23, and the control valve is operated to reverse the flow in the main hydraulic circuit so that the drill carriage is withdrawn. During the return movement, the piston again slides over the rod until it contacts a fixed stop on the rod and moves the rod rearwardly to restore the toggle to its original position so that a new cycle of operations commences, the piston gripping the rod again at a point rearward of the initial gripping point. Specification 634,457 is referred to.
